A program for improving student social skills was implemented in three classrooms of lower-class kindergarten and second grade students at two schools in order to reduce the number of behavior problems. Student behavior is a nationwide educational concern, and the problem of inappropriate behavior at the schools was documented by teacher observation (using a behavior checklist), discipline related contacts with parents, and the number of discipline referrals. The literature suggests causes for the behavior problems include students' lack of social skills, lack of positive role models, lack of self-esteem, and lack of positive parental involvement; media violence; and childhood abuse. An action plan for intervention was implemented to increase social skill development through direct instruction, conflict resolution, role playing, modeling, and cooperative learning opportunities. Post-program data (utilizing teacher observation, parent contacts, and discipline referrals) indicated an increase in appropriate behavior and in interpersonal skills. (Twelve appendices include checklists, forms, charts, book lists, suggested books and cassettes, cooperative learning lessons, and a description of learning centers. Contains 40 references.) (TM)
